Jurors took just 10 minutes Wednesday to convict Clair Wolf, 66, of trying to hire a hit man last year to kill his two sisters and a brother-in-law.

The bombing took place two years before the unemployed truck driver tried to hire an inmate at the Harris County Jail to kill family members, but both were violent attempts to end an acrimonious inheritance fight, investigators said.

Because Wolf was convicted after two days of testimony this week, the jury heard evidence Thursday to decide his punishment, which ranges from five years to life in prison.

Vennie Wolf was the first witness in the punishment phase, and jurors heard about severe burns, cuts and scrapes she endured when tacks, glass and pieces of pipe hit her in the explosion.

"My eyes were already swollen shut," Vennie Wolf testified about the aftermath. "My leg had severe gashes in it, and I knew I could bleed to death from the leg."

Clair Wolf's attorney, Sid Crowley, had argued that the inmate who turned Wolf in was lying about the allegations.

In closing arguments scheduled Friday, he is expected to tout Wolf's accomplishments, including military service in Vietnam.
